[LayoutNG] Remove style_ and layout_result_ members on NGBlockNode.

[LayoutNG] Remove style_ and layout_result_ members on NGBlockNode.

They aren't really needed now. Eventually we'll want NGBlockNode to just
be a POD around the layout object to remove overhead.

After this we can transition NGBlockNode to just be a POD (NGInlineNode
needs a bit more work).

I don't know if this mucks up your cache work; but my thought is that we shift
the storage for that onto LayoutBoxRareData or similar?

[cbiesinger, 2017-03-02 22:26:07]

lgtm, I don't think I'll need these
